CVE-2026-95604: Loops & Logic Auth Bypass Vulnerability

CVE-2026-95604 Overview

CVE-2026-95604 is an unauthenticated broken access control vulnerability affecting the Tangible Loops & Logic plugin for WordPress in versions up to and including 4.2.4. The flaw stems from missing authorization checks [CWE-862], allowing remote attackers to reach functionality that should be restricted to privileged users. Exploitation requires no authentication, no user interaction, and can be performed over the network. Successful exploitation results in disclosure of information that the plugin should protect. The issue was published to the National Vulnerability Database (NVD) on 2026-09-23.

Critical Impact

Unauthenticated remote attackers can bypass access controls in the Loops & Logic WordPress plugin to expose confidential data handled by the plugin.

Affected Products

• Tangible Loops & Logic plugin for WordPress
• All versions up to and including 4.2.4
• WordPress sites with the vulnerable plugin installed and active

Technical Details for CVE-2026-95604

Vulnerability Analysis

CVE-2026-95604 is a broken access control weakness in the Tangible Loops & Logic WordPress plugin. The plugin exposes functionality that fails to verify whether the caller holds the required capability or role before executing sensitive actions. An unauthenticated attacker can issue crafted HTTP requests directly to the affected endpoints and receive data that should be gated behind an authorization check.

Because the flaw is reachable across the network without credentials, any WordPress installation running a vulnerable version and exposed to the internet is at risk. The vulnerability affects confidentiality only, with no direct impact on data integrity or site availability according to the published CVSS vector. The scope of exposed information depends on how site owners have configured the plugin and what data is rendered or queried through the affected handlers.

Root Cause

The root cause is a missing authorization check [CWE-862] on one or more plugin request handlers. The code path executes privileged logic without calling WordPress capability checks such as current_user_can() or verifying a valid nonce. As a result, the request handler treats anonymous callers as authorized to perform actions intended for administrators or logged-in users.

Attack Vector

An attacker sends unauthenticated HTTP requests to a vulnerable WordPress site hosting the plugin. No account, session, or user interaction is required. The attacker targets the plugin endpoint directly to trigger the unprotected functionality and retrieve sensitive data returned by the response. Refer to the Patchstack Vulnerability Advisory for further technical context.

No verified public exploit code is available for CVE-2026-95604 at time of writing. The vulnerability mechanism is described in prose based on the advisory metadata rather than reconstructed exploit payloads.

Detection Methods for CVE-2026-95604

Indicators of Compromise

• Anonymous HTTP requests targeting Loops & Logic plugin routes, admin-ajax.php actions, or REST endpoints registered by the plugin
• Unusual response sizes returned to unauthenticated clients from plugin endpoints
• Repeated requests from a single source enumerating plugin parameters or object identifiers

Detection Strategies

• Inventory WordPress sites and identify installations running Tangible Loops & Logic at version 4.2.4 or earlier
• Review web server access logs for unauthenticated requests to plugin URLs that return HTTP 200 with non-trivial payloads
• Correlate WordPress wp-admin/admin-ajax.php and REST API traffic against source IP reputation and geolocation baselines

Monitoring Recommendations

• Enable verbose access logging on the WordPress reverse proxy or web server for plugin endpoints
• Deploy a web application firewall (WAF) rule to alert on unauthenticated calls to Loops & Logic handlers
• Track plugin version drift across the WordPress estate to catch sites that lag behind the patched release

How to Mitigate CVE-2026-95604

Immediate Actions Required

• Update the Tangible Loops & Logic plugin to a version later than 4.2.4 as soon as the vendor publishes a fixed release
• Audit user roles and any content the plugin renders to determine the sensitivity of potentially exposed data
• Restrict administrative access to WordPress and rotate any secrets that may have been exposed through plugin output

Patch Information

Refer to the Patchstack Vulnerability Advisory for the current patch status and the fixed version once published. Apply the vendor-supplied update through the WordPress plugin manager or by deploying the patched release across all affected sites.

Workarounds

• Temporarily deactivate the Loops & Logic plugin on affected WordPress sites until a patched version is applied
• Block unauthenticated access to plugin routes at the WAF or reverse proxy by requiring an authenticated session cookie
• Limit exposure of the WordPress admin surface using IP allowlists for /wp-admin/ and /wp-json/ endpoints

# Example nginx snippet to restrict plugin endpoints to authenticated sessions
location ~* /wp-json/tangible/ {
    if ($http_cookie !~* "wordpress_logged_in") {
        return 403;
    }
}
